MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611106955 A) filed by Chandigarh University on September 05, 2026, for Passive Retrofit Cyclonic Grease Separator For Wall-Mounted Exhaust Fans.
Inventors include Arnav Bansal; Shonak Bansal; and Parveen Tyagi.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention provides a passive, modular grease separation apparatus configured for retrofit installation onto standard residential wall-mounted exhaust fans. The apparatus comprises a convex aerodynamic dome housing, a plurality of tangentially angled peripheral slits, and an integrated gravity-fed collection receptacle. The apparatus operates without internal moving parts and utilizes the suction generated by the downstream exhaust fan to draw grease-laden kitchen air through the tangentially oriented slits. The geometric arrangement of the slits induces rotational airflow within the dome, thereby generating a vortex that promotes centrifugal separation of entrained grease droplets and particulate matter. The separated contaminants are directed toward the inner surface of the dome, where they coalesce and flow downward under gravity into the collection receptacle. The apparatus thereby reduces grease deposition on fan blades and motor components, facilitates periodic cleaning, and enhances operational safety and service life of wall- mounted exhaust fans.
